조선후기 楓橋夜泊圖 연구

장계수 한국고전번역원 2023 民族文化 Vol.65 No.-

This study aims to examine "Punggyoyabakdo(楓橋夜泊圖)" drawn by borrowing a poem as its topic(畫題) in the late Joseon period, when the poem “Punggyoyabak(楓橋夜泊)” by the Tang poet Zhang Gye(張繼). Began to attract the attention of the past numerous writers after the Song literary man Ouyang Xiu(歐陽修: 1007-1072) critically mentioned that there was a problem with the lines of this poem of Zhang Gye’s. Many Chinese writers, including Bo Juyi(白居易) and Wen Tingyun(溫庭筠), as well as Goryeo and Joseon writers, borrowed this poem by Zhang Gye. In this way, Zhang Gye’s poem had been known from earlier years, but it was widely loved in the late Joseon period was the desire for Gangnam(江南), China. Also presumably, because his poem contains two poetic words, "Gososeong (姑蘇城)" and "Hanshansi(寒山寺)," both of which are reminiscent of Suzhou(蘇州), the hub of the southern region of the Yangtze River in China. There is a record on the production of "Punggyoyabakdo" in Chimwudangjip( 枕雨堂集 ) compiled by Jang gjwan(張之琬: 1806-?) in the late Joseon period. This record features in detail the production of the drawing in which the topic of “Punggyoyabak” is borrowed, the artist who painted the work, the content of the topic, the painting method, and the evaluation of the time. Through this, it could be assumed that "Punggyoyabakdo" was painted by Jang Deokju(張德胄: 1756-1821) in the late Joseon and that the work was a landscape-portrait painting in the Yuan artist Yechan(倪瓚: 1301-1374)’s style. In late Joseon, the painting "Punggyoyabakdo" started by borrowing the topic of the poem. It also shows a variety of production aspects, including temple murals and blue-and-white porcelain landscape patterns. In particular, "Punggyoyabakdo"of the late Joseon period came to be included in the representative landscape painting “The Eight Views of the Xiao-Xiang Rivers," which was transformed into “Punggyoyabak(楓橋夜泊) = Hansamojong(寒山暮鐘)” instead of “Yeonsamojong(煙寺暮鐘)” so it became the subject of the Eight Views of the Xiao-Xiang Rivers. This transformation is deeply related to the its popularity among people in which the verse of “Punggyoyabak” was accepted into Sijo, the Pansori saseol, Danga(短歌) <Eight Views of Xiao-Xiang Rivers(瀟湘八景歌)> and sung as song widely. The conclusion is that this study is meaningful in that the actual aspect of "Punggyoyabakdo" of the late Joseon period has been explored through its records of production and remaining works.

Objectives: The purpose of this study was to examine the satisfaction level of students with a job tour program and their major and their adaptation to their major in an effort to provide some information on student guidance and the improvement of dental hygiene education. Methods: The subjects in this study were 269 freshmen to find out their views of job tour and the relationship of their general characteristics and motivation of major choice to satisfaction level with their major and adaptation to the department, t-test and one-way ANOVA were carried out. And correlation analysis was made to look for connections among major satisfaction, major adaptation and satisfaction with job tour. Results: 1. As for the choice of major, the biggest group of 128 students (47.6%) made a decision on their own. 2. In regard to satisfaction level with their major, the freshmen got 3.55±0.67, and the sophomores got 3.36±0.66. There was a significant difference according to academic year(p<0.05). 3. Concerning the links between motivation for major choice and major satisfaction, the students who chose their major in consideration of their own aptitude or personality got the highest marks of 3.96±0.64(p<0.05). 4. As to satisfaction level with the job tour program, they were most satisfied with field trip(4.03±0.74). 5. Regarding the correlation among major satisfaction, major adaptation and satisfaction with the job tour program, there was a significant correlation among all the variables(p<0.01). Conclusions: The students who gave priority to their own aptitude and personality in choosing their major were more satisfied with their major and were better adapted to that. Therefore it`s required to consider how to boost the satisfaction level of students with their major and their adaptation to that.

Research on data-based fault diagnosis models is being actively conducted in various industries. However, in the case of industrial equipment, various operating conditions occur, and it is difficult to secure sufficient training data. To solve this problem, a cross-domain adaptation technique can be utilized. In this study, we propose an adversarial consistency-maintaining transformation learning method that can maintain failure classification consistency even for the new untrained environmental data using the rotating body vibration data. The data generated through consistent learning creates a continuous invariant latent space between the new operating condition data distribution and the known data distribution and learns to maintain the failure classification performance through an adversarial learning network that shares the failure classification characteristic nformation. Therefore, the proposed method can provide a more stable and general classification performance by expanding the potential space to minimize the discrepancy between domain data. The experimental results of the proposed model showed about 88% accuracy for a real-machine dataset, and compared to the existing cross-domain adaptive learning methods, it showed a performance improvement of about 5-10%. According to the results of this study, it is expected to be an effective solution for the problem of equipment failure diagnosis at actual industrial sites. 다양한 산업분야에서 데이터 기반의 고장 진단 모델에 대한 연구가 활발히 이루어지고 있다. 그러나 산업 장비의 경우 다양한 운행 조건이 발생하고, 이에 따른 충분한 훈련 데이터 확보가 어렵다는 문제가 있다. 이러한 문제를 해결하기 위해 교차-도메인 적응 기법을 활용할 수 있다. 본 연구에서는 회전체 진동 데이터를 사용하여 학습되지 않은 새로운 환경 데이터에 대해서도 고장 분류 일관성을 유지할 수 있는 적대적 일관성 유지 변환 학습 방법을 제안한다. 일관성 유지 학습을 통해 생성된 데이터는 새로운 운행 조건 데이터 분포와 이미 알고 있는 데이터 분포 간의 연속적인 불변 잠재 공간을 생성하고, 고장 분류 특징 정보를 공유하는 적대적 학습 네트워크를 통해 고장 분류 성능을 유지하도록 학습한다. 따라서 제안된 방법은 도메인 데이터 간의 불일치를 최소화할 수 있는 잠재적 공간을 넓힘으로써 보다 안정적이고 일반적인 분류 성능을 확보할 수 있다. 제안한 모델의 실험결과는 약 88%내외의 성능 평가가 이루어졌으며, 기존 교차-도메인 적응 학습 기법들과 비교하여, 약 5~10%의 성능향상을 보였다. 이러한 연구 결과로 실제 산업현장에서 겪는 장비 고장 진단 문제의 효과적인 해결방안이 될 것으로 기대된다.

This paper proposes an improvement plan for a groundwater facility survey method that is closely related to public health and life. The government manages areas that need to secure water resources due to drought in accordance with Article 9-6 of the Groundwater Act, promoting and carrying out projects for the installation and management of facilities to secure groundwater resources. In this study, we implement an integrated system that can utilize a Global Navigation Satellite System (GNSS) for precise location information, and to collaborate with sites in real time. By applying IT to groundwater facility surveys, the reliability of the collected data can be secured, and work efficiency increased. Collecting time series data provides a way to minimize job vacancies for field surveyors whose job volatility is high. In addition, input data are standardized so the constructed data can be used in a big data system, and metadata is also rated in order to increase information utilization.

ABSTRACTThe corrosion of silver amalgam is regarded as one of major causes in the failures of' dental amalgam restorations. To evaluate the corrosion resistance of dental amalgam alloys, electrochemical tests such as potential and polarization measurement were used widely. But these commonly used methods have not provided the sufficient informations on relative resistance of amalgam to corrosion.In this experiment, the corrosion currents were measured using electronic potentiostat to compare some commercial dental amalgam alloys. All alloys were triturated in a amalgamator and condensed into a mold described in A.D.A.specifiction No.1 to produce cylinder form specimens of 4mm diameter by 5mm long. After specimen kept for 1 week at 37"C, each specimen was embedded in epoxy resin. The surfaces of specililens were then polished luith a emery paper, diamond dust, and Al203. These specimens were immersed in artifical saliva kept at 37"C, and currents of each specimen were measured for 24 hours at 0. 0volt (SCE).The author obtained conclusions as follows : 1. High copper amalgam showed superior resistance against corrosion to conventional amalgam, but a pellet form of high copper amalgam seemed to be susceptible to corrosion. 2. In lathe-cut alloys, fine·cut had superior resistance against corrosion to regular-cut. 3. Non-zinc conventional amalgam alloys were more resistant to corrosion than that of zinc containing conventional amalgam alloys. 4. In both of high copper and conventional amalgams, predispensed forms tended to have better resisitance to corrosion than that of pellet forms.

인제·속초(01-05) 소권역중 대표단위인 신선봉 지역을 중심으로 2002년 5월부터 9월까지 6회에 걸쳐 채집, 조사하였다. 신선봉과 인근 마산, 780고지에서 채집된 식물은 모두 62과 151속 231분류군이었다. 본 조사 지역에서 확인된 특정식물종 5등급에 해당하는 종은 발견되지 않았으며, 4등급 7분류군, 3등급 9분류군, 2등급 9분류군, 1등급 14분류군으로 모두 39개 분류군의 특정식물종이 확인되었다. 특히 조사 소권역중 대표단위인 신선봉의 경우 총 36개 분류군의 특정식물종이 관찰되었다. 확인된 특정식물종을 등급별로 나누어 등급별 종수와 등급별 평가점수를 곱하여 합산한 산지별 평가점수는 소권역 전체의 총점이 174점이었고 신선봉이 160점으로 가장 높았으며 마산 24점, 780고지 6점의 순으로 나타났다. 조사 권역에서 발견된 특정식물종 중 4등급에 해당하는 눈측백나무, 등대시호, 회리바람꽃, 앉은부채, 꽃개회나무 등은 신선봉 지역에서 발견된 종들로 대부분 인적이 드문 곳에 위치하여 인위적 및 자연적인 위협 용인이 존재하지 않는 것으로 판단된다. This study was carried out to investigate the flora of Mt. Sin-sun-bong (alt. 1,204m) and adjacent regions located on the northern side of Seol-at National Park, in province Gangwon-do, from April to September, 2002. The purpose of our study was to enlist vascular plant species of Mt. sin-sun-bong, Ma-san (alt.1,252m) and 780 peak (alt. 780m) and to inventory rare and endangered plants. During the exploration, we found 62 families, 151 genera, and 231 taxa (including species, subspecies, varieties and forma). The flora of Mt. Sin-sun-bong included thirty-nine taxa as the endangered species. Each sites were scored by the standard points, and these were estimated by the multiplication the number of taxa as their grade. It was shown that the evaluation points of Mt. Sin-sun-bong had the highest score, 160 points, following by Ma-san (24 points) and 780 peak (6 points). Five species (Thuja koraiensis Nakai, Anemone reflexa Steph. et Willd., Bupleurum euphorbioides Nakai, Symplocarpus renufolius Schott, Syringa wolfii C.K. Schneid.), of the 4th level of conservation priority. However, it seems to be no apparent artificial and natural threat at hand.
